HISTORIC RANKINGS Historic Rankings: These are rankings of streams from historical studies. "Yes" means the stream was considered worthy of protection by that method. Some methods include non-biotic data in their determination. See Atlas Key for details.

Multi-Attribute Prioritization of Streams - Potential Heritage Streams (1998): No Hawaii Stream Assessment Rank (1990): Without Data U.S. Fish and Wildlife Service High Quality Stream (1988): No The Nature Conservancy- Priority Aquatic Sites (1985): Yes National Park Service - Nationwide Rivers Inventory (1982): No

Current DAR Decision Rule Status: The following criteria are used by DAR to consider the biotic importance of streams. "Yes" means that watershed has that quality.

Native Insect Diversity Native Macrofauna Absence of Priority 1 > 19 spp. Diversity > 5 spp. Introduced No No No

Abundance of Any Presence of Candidate Endangered Newcomb's Native Species Endangered Species Snail Habitat No No No
